Eurogamer: The townsfolk have been listening to Shepard pulling the old "Commander who shouted 'Reaper!'" ruse for some time now. First she (he, if you're feeling obtuse) shouted 'Reaper!' when she discovered that the caretakers of the Galaxy were about to sweep up all known galactic civilizations. Then, in Mass Effect 2, she shouted 'Reaper!' after she'd fought against a big icky monster that had been made from human body parts, and had all/most/some of her underlings killed in the process.
